Its for sure I have developed a paper template of which I think will work.
I have a Fiskars Shapes 1 template with and oval 2.75" x3.5" or 69.85 mm x 88.9 mm which is a reasonable size.
Using a A4 5mm grid sheet I developed the profile Then with a second piece formed a corner its not exactly aligned but its enough to see it will work. The intention is to bandsw the elipse lines and produce two router templates and determine table top dimensions Stand by for a 2026 Victorian Table Replication
From what I have found out one exists in the Brisbane parliament (according to a Google image search) and made by a crafstian by the name of John Peterie possibly now deceased. (being 19 century)
Extract However, historical records highlight that John Petrie, a prominent Brisbane craftsman and builder, played a significant role in creating furniture for the Queensland Parliament in the 19th century.
Not sure who knocked up the one in Canterbury for Sarah, but if I am successful I will call it the Sarah Mullally Table !! with credits to John Petrie.
